All Implemented Interfaces:

PKCS11EngineClass

public class Des2KeyGenerator
extends PKCS11KeyGenerator

This is a key generator that generates double-length DES keys on a token. Through a PKCS11KeyGenerationSpec parameters object, the application can control the generation of keys; e.g. give a key template.

The supported key sizes are 112 and 128 bit, default is 112 bit. Both values result in key with 128 bit but 112 effective key bits.
